I have a sensitivity to certain cooking fumes. I've tried to assess it objectively like it's a nocebo, which would be great if it were. There are two cafes in SF I used to frequent who do their cooking in the same main space as guests, do not have much if any ventilation, and, if I was there hacking on my laptop around lunch time, I would always get headaches and need to leave. (one is a trendy workspace cafe, that I feel bad naming). It has not happened at other SF cafes despite a lot of working-in-cafes. I also used to have a roommate who didn't like the sound of our ventilation fan and wouldn't open the kitchen back door (to the outdoors) because of the cool air. Anytime she cooked with the oven I would get a headache and need to leave the apartment, while having no problem with the third roommate's cooking who preferred to ventilate.
